Ricoh Theta Z1 is the only 360 camera with 1-inch sensors, the largest among consumer or prosumer cameras. It is one of the best choices for virtual tours, thanks to its convenient Lightroom-based workflow for Raw DNG editing. At the same time, for anyone who does not want to edit 360 photos, the Z1 has the best quality straight out of the camera, with nearly perfect stitching and excellent built-in HDR.
